Exposes monitoring information about an ongoing and potentially long-running administrative process. This should be taken to mean, at minimum, any OA&M operation involving I/O. Examples include starting and stopping servers, deploying and undeploying applications, or migrating services.
An MBean operation of this sort should fork a separate thread to perform the actual work and immediately return an instance of TaskRuntimeMBean to the caller. The caller can then use this to track the task's progress as desired. Users can also query for all instances of TaskRuntimeMBean to get a summary of both currently-running and recently-completed tasks.
Instance of TaskRuntimeMBean continue to exist in the MBeanServer after the completion of the work they describe. They will eventually either be explicitly deregistered by the user, or removed by a scavenger process which periodically purges TaskRuntimeMBeans that have been completed for some time.

|
An array of TaskRuntimeMBeans that describes a set
of parallel tasks which are components of this task.
A value of null indicates that this task has no
subtasks.
A simple example of a task with subtasks would be one which monitors a user's request to start a cluster; that task should return a set of subtasks indicating the individual server-startup processes which compose the overall cluster-startup task.
| Factory Methods | No explicit creator method. The child shares the lifecycle of its parent. |
